Questions

I want to report a bug.

Please use GitHub issues.
I want a feature.

Chances are I'm too busy to work on features I don't personally need, so pull requests are strongly encouraged.
Why not aegisub?

Because it doesn't cover my needs, it's too convoluted and its development is too slow.
Windows builds?

You can find a Windows build for bubblesub here.
I don't maintain it, so please contact the current developer if you find some issue.
Versioning? PyPI?

I don't say no, maybe in the future, if the project gets more popular. For now, git master is the way to go.

ass_tag_parser's Issues

Don't raise an exception, simply have a class for unknow tag

Currently, ass_tag_parser can't parse VSFilterMod tag which is totally ok, because they have they are useless.

But, it would be better if it could not raise an exception. It should simply have a class for unknowtag.

Here is the code I have:

result = parse_ass(
    r"{\fnJester\fsc20}test"
)
print(result)

What it currently does:
ass_tag_parser.errors.BadAssTagArgument: syntax error at pos 16: \fs requires an integer

What it could do:
[AssTagListOpening(), AssTagFontName(name='Jester'), AssUnknowTag(text=fsc20), AssTagListEnding(), AssText(text='test')]
